Which configuration should I pick?
Most buyers choose the recommended kit: Gel batteries. It is the kit TASKI recommends for this machine.
Gel batteries: sealed and maintenance free (no watering). Lower price than lithium.
Lithium batteries: no watering, can be charged at any break (opportunity charging), lighter and longer service life. Higher price.

Frequently asked questions
What does an orbital deck do? An orbital deck moves the pad in small, fast circles instead of spinning it. This gives an even scrub and is often used for deep cleaning and finish removal with less water and chemical.
How much floor can it clean per hour? About 18,170 sq ft per hour in real use (TASKI practical figure). The theoretical maximum is 24,219 sq ft per hour.
How long does the battery last? Up to 4 hours (TASKI figure).
Gel or lithium: which battery should I choose? Gel costs less and is maintenance free. Lithium costs more, but it charges faster, you can top it up at any break, and it lasts more charge cycles. If you clean in one long shift and charge overnight, gel is usually enough. If you clean in several shifts, choose lithium.
How does it ship? Machines this size ship by freight on a pallet. Tell us if you need a liftgate or inside delivery when you order. Call 877-449-0447 for a freight quote to your zip code.
